Question

How does a protein change during denaturation and why is this important? a. the protein loses amino acids; the polarity may be changed b. the protein loses its shape; the protein cannot function c. the protein loses HOH; dehydration synthesis cannot occur d. the protein gains amino acids; the protein changes into a different protein (1 point)
Responses

the protein loses amino acids; the polarity may be changed
the protein loses amino acids; the polarity may be changed

the protein loses its shape; the protein cannot function
the protein loses its shape; the protein cannot function

the protein loses HOH; dehydration synthesis cannot occur
the protein loses HOH; dehydration synthesis cannot occur

the protein gains amino acids; the protein changes into a different protein

Answer 1

b. the protein loses its shape; the protein cannot function

Explanation: Denaturation disrupts the protein's secondary, tertiary, or quaternary structure (folding) without breaking the peptide bonds between amino acids. Losing its proper shape prevents the protein from performing its specific function (e.g., enzyme active site no longer fits substrate).
